Is what you call "ejector pit" a pipe or hole to drain the water out of a sump tank ?Following on the "finishing a basement bathroom" subject I have a question ..... there is a sump hole in my basement, no pump was there when I bought the house. But I never had flood problems or accute humidity in the basement so far. I use a dehumidifier during the summer and I need to drain its water . I want to drain into the sump tank but afraid that without the sump pump the water may rise over the floor level.My questions are:How do I identify the drainage pipe out of the sump hole ?Will it be possible to stay with the sump hole without sump pump and have the water drained out with the help of some build-in pipe which I find hard to identify ? How do I test the capacity of natural drainage without sump pump ?ThanksReuven
